Clinical Features

Differential Diagnosis

Extremity trauma



Prehospital Proticol for Entrapment Lasting >4hrs or Suspicion of Hyperkalemia

Should begin BEFORE extrication

  • Cardiac monitoring
  • Hydration (~NS 1.5 L/hr)
  • Pain control
  • Albuterol neb
  • Calcium chloride
    • 1 gram slow IV push over 60 sec
  • Sodium bicarbonate
    • Flush IV with NS (prevent precipitation), then
    • 1mEq/kg added to 1L of normal saline, run IV wide open just prior to extrication
  • Release compression
    • In the field, use of tourniquet before extrication is controversial
